We have been at this time of year twice-2005 and 2006 (missed last year). we are going again this year. Weather was great both times for us, a little warmer in 06 (we went mainly for the halloween party, although we stayed a week and did food and wine festival things as well). Our son and one of his friends went as Hans and Franz, and the sweatsuits got really hot before the night was over. I was very comfortable as little red riding hood. Be sure and bring costumes for the whole family, there are a lot of folks who dress up. That said, since it can be warm, I don't think I would get one of those fake fur animal suits (pooh, eeyore). Think lighter weight, and have a great time!
